Speaking involves the vocalized production of language in real time through the use of the speech organs. It is the hardest of the four language skills due to the limited time for planning. Speaking requires conceptualizing ideas, formulating them syntactically and lexically, articulating sounds, self-monitoring, and employing fluency strategies like pausing, fillers and prefabricated language chunks. Fluency depends on factors like speech rate, length of pauses, and use of fillers. Successful speaking also requires turn-taking skills and knowledge of genres, contexts, and social relationships.
